libwebrtc.dylib contains a global initializer: $ nm -j libwebrtc.dylib | fgrep __GLOBAL__ __GLOBAL__sub_I_logging.cc This appears to be the initializer for g_log_crit and LogMessage::streams_ in webrtc/base/logging.cc These things should be initialized lazily so that not every executable that links against WebKit pays the launch-time cost of initializing them.
